Cell-Cell Flashcards
(20 cards)
Epithelium
A tissue that forms external and internal surfaces
Extracelluar matrix
A fiber composite in animal cells
What does the Extra cellular Matrix do?
The ECM provides support, allows for communication, and is connective tissue
What is the ECM made of?
It is mainly made of the cable-like protein, collagen
Is the ECM dynamic?
The ECM is dynamic
Protein that is found in many anchoring junctions
Cadherins
Mechanically attach cytoskeleton to adjacent cells or extracellular matrix
Anchoring Junctions
Protein that is found in gap junctions
Connexons
Prevents small molecules form leaking between cells
Tight Junctions
A form of communication only present in plants
Plasmodesmata
Permits free passage of ions and small molecules between cells
Communication Junction
What type of protein is use to transduct?
Protein kinase
What molecule appears right before the shape of a cell changes?
Myosin
What is integrin?
Integrin is a receptor or transmembrane protein
Glycportein
Made of protein and sugar
What is collagen
Collagen is a long fiber protein. most abundant in the body.. it makes up bones and tendons
What is a type of communication junction that is anchored to intermediate filaments
desomosomes
ECM cross linking proteins
Laminins
What are information carrying molecules
hormones
When signals from different pathways interact to modify the cells response
Cross talking
